Nats question and HFS?

[Cleo]

I've just been using my unencoded ID when adding in HFS but now I'm not sure if I'm actually getting credit for sales from them.

This is mostly concerning using links supplied by hfslinks.com where we just put in our ID and it returns a list of links.

I notice that
http://free.ocxxx.com/sites/18i/01mo...cfrevshare:18I
sets a cookie as soon as I click on an ad

But I noticed that
http://free.ocxxx.com/sites/18i/01movies/?nats=sexycleo
doesn't set a cookie until I click through to the join page.

Also if you look at the URL after clicking on an ad all I see is the site URL in the second case.
